Parental and Child Self-Efficacy Explaining Food Intake through Self-Regulation: A Dyadic Prospective Study

According to social cognitive theory and socio-ecological models, self-efficacy and temptation-related self-regulation (the use of distraction or suppression) are modifiable predictors of health behaviors, such as food intake. Yet, there is limited evidence explaining how these factors are interlinked among parent-child dyads. This study investigated indirect effects of parental and child self-efficacy on food intake, via parental and child self-regulation.

The prospective study (the baseline [T1] and the 10-month follow-up [T2]) enrolled 924 parent-child dyads (1,848 individuals; 54.3% girls, aged 5-11 years, 88.9% mothers). Dyads were interviewed or completed self-report measures. Path analyses with maximum likelihood estimation were conducted.

Child self-efficacy and distraction (T1) mediated between parental self-efficacy (T1) and higher levels of child fruit and vegetable intake (T2). No significant mediating effects of suppression were found, nor indirect effects of parental self-efficacy (T1) on energy-dense food intake (T2).

Health promotion interventions aiming at changing fruit and vegetable intake among 5-11-year-old children should target enhancing parental and child self-efficacy that may facilitate the use of self-regulation and, in turn, healthy diet.
